Quasi-Periodic Peak Energy Oscillations in X-ray Bursts from SGR J1935+2154

Oliver J. Roberts, Matthew G. Baring, Daniela Huppenkothen +6

Magnetars are young neutron stars powered by the strongest magnetic fields in the Universe (10 G). Their transient X-ray emission usually manifests as short (a few hundre…

The 2022 high-energy outburst and radio disappearing act of the magnetar 1E 1547.0-5408

Marcus E. Lower, George Younes, Paul Scholz +19

We report the radio and high-energy properties of a new outburst from the radio-loud magnetar 1E 1547.05408. Following the detection of a short burst from the source with Swift-…
